WebGL GPU Test
Check your GPU WebGL capabilities, supported extensions, and rendering information.
WebGL version, renderer name, vendor, supported extensions, and max texture size. Click Start Test; GPU information is collected from the WebGL context automatically.
What does this test measure?
WebGL version, renderer name, vendor, supported extensions, and max texture size.
Why is this test important?
Check your GPU WebGL capabilities, supported extensions, and rendering information.
How do you run the test?
Click Start Test; GPU information is collected from the WebGL context automatically.
How should results be interpreted?
More supported extensions and higher limits indicate a more capable GPU and driver.
Normal and problematic results
More supported extensions and higher limits indicate a more capable GPU and driver.
Technical limitations
Some browsers hide the renderer name for fingerprinting protection.
Why can the score decrease?
Unstable measurements, denied permissions, unsupported browser APIs, background load, power saving, or an incomplete test can affect the result. When a score changes, the result screen explains the reason.
What should you do if a problem is found?
Update GPU drivers, or switch to a browser with full WebGL support.
Example Result Explanation
Frequently Asked Questions
Does this test provide a definitive hardware diagnosis?
No. The test measures signals the browser can safely access and clearly explains its technical limits.
Why can results change between runs?
Background applications, power mode, network conditions, permissions, and operating-system timing can affect results.
How should I repeat the test if I see a problem?
Repeat it on the same device and browser while changing only one condition, so the source of the difference is easier to identify.
